What is a reverse DNS record?
A reverse DNS record (also know as a PTR record), is a reverse mapping from IP to name. For instance, when a lookup is made on the IP of 126.96.36.199, it should come back with host.mydomain.com. It is a very good idea to have the hostname of your server match the PTR record assigned to it’s IP. This can only be changed by the owner of the IP address
